lpm6: fix compilation with -Og
The compilation with gcc-6.3.0 and EXTRA_CFLAGS=-Og gives the following error: CC rte_lpm6.o rte_lpm6.c: In function ‘rte_lpm6_add_v1705’: rte_lpm6.c:442:11: error: ‘tbl_next’ may be used uninitialized in this function [-Werror=maybe-uninitialized] if (!tbl[tbl_index].valid) { ^ rte_lpm6.c:521:29: note: ‘tbl_next’ was declared here struct rte_lpm6_tbl_entry *tbl_next; ^~~~~~~~ This is a false positive from gcc. Fix it by initializing tbl_next to NULL.
